A module is a software unit that groups a set of data structures and subprograms/routines, which are typically cohesive. Modules are entities that are separately compiled by programmers to make them reusable. This allows programmers to work of different modules simultaneously. Modules promote two important elements of software programming:
- Encapsulation (also called as information hiding)
These elements make complex programs simpler to grasp. Most programs are composed of one or more modules that are developed independently. To explain modules in a detailed manner, we will take the example of the Perl module.About the Author:
The Perl Module:
A Perl module is a separate component of program for the Perl programming language. As you know Perl allows many different style of programming. You will find a module written as object-oriented (like the XML-Parser) or in a procedural style (e.g. Test-Simple). Modules in Perl language can also be used to change the syntax of the language or for mixing methods.
A collection of one or more modules, including build scripts and documentation, compose a distribution. The Perl programming community has a huge library of distributions.
Software development companies build modules for software like Drupal or Perl or Joomla that extends, and enhances the core functionality of these programs. Take the example of Drupal. Drupal boasts many modules that extend its functionality in many ways. The modules are used to make web development a pleasurable experience. There are ecommerce modules that can add product catalogues and shopping cart for your site or a payment gateway. Some modules add embargo and expiry times for web pages.
A software development service builds the right module for programs. Whether it is a translatable module or 404 Blocks, you will find the module of your choice. You can also download modules from dedicated sites that allow free downloadable content. Some software development companies also build game modules exclusive for clients.
If you are interested in a unique module for a particular site or program, make sure you heed the suggestions and recommendations of a software development consulting firm.
